Did the "bzr: ERROR: Connection closed: ..." message appear when you did 'bzr break-lock", or when you did "bzr ci", or both times?
This looks quite like a bug that was fixed ages ago (in 2.1.0b2), but you are using bzr 2.2b2 so that shouldn't be it. Hmm!
If you can reproduce it then please run "bzr -Dhpss ci" and then attach the contents of the bzr.log file ("bzr --version" will tell you where to find it").
